If you ammortize the environmental impact of building the rail network over all the rail trips, it might swing the other way. Especially if someone figures out carbon neutral air travel in the next decade.

If we are factoring in imaginary future tech then someone could invent carbon neutral trains

That's theoretically true, but more far-fetched considering the amount of steel involved.

Synthesizing jet fuel from atmospheric carbon, directly or indirectly, is an active area of research and will likely happen at some point.
